Pipeline expansion joint performance and characteristics?

Pipe expansion joint is a connection that compensates for the dimensional changes caused by thermal expansion and contraction in pipe connections. There are two kinds of pipeline expansion joints commonly used, one is rubber pipeline expansion joint and the other is metal pipeline expansion joint.
 
Rubber pipeline expansion joint features.
One, work to reduce the structure to transmit noise, vibration absorption capacity.
Second, small volume, light weight, good elasticity, easy installation and maintenance.
Third, the installation can produce axial, transverse, longitudinal, angular displacement, not subject to the restrictions of the user's pipeline is not central, flange is not parallel.
Fourth, with special synthetic rubber can be high temperature, acid and alkali resistance, oil resistance, is the ideal product for chemical corrosion resistant pipeline. The main features of metal pipeline expansion joint are large expansion and contraction compensation, withstand high temperature and high pressure.
 
Installation of steel expansion joints have strict regulations, installation should pay attention to the setting of fixed bracket and force, hitting pressure shall not be cracked due to fixed bracket and cause expansion joint expansion end pull out; shall be designed by the design department to install, otherwise the pipeline is prone to problems. Pay attention to the setting distance of the guide bracket, a very good guide bracket should be installed at a distance of 4D (4 times) from the compensator, two guide brackets should be installed at a distance of 14D from the compensator, point three can be set arbitrarily.
 
The demolition joint can relieve the blind thrust in the pipeline operation, however, at the pump outlet and at the corner of the pipeline, the sliding pipeline connection without fixed piers, infinite piers and directional limit piers bracket should be used in the C2F type demolition joint and CC2F type demolition joint to avoid the thrust concentrated at the corner of the pipeline or near the end of the pump and the impact force damage to the equipment. In fact, in the use of various pipelines, or the use of limit expansion joints and anti-pull-off limit rubber joints, the pipeline plays a certain protection, especially for the installation and maintenance of the pipeline provides a convenient.
